Be it known that I, OSCAR L. NEANDER, a citizen of the United VStates, residing, at Aurora, inV the county ofv Hamilton and State of Nebraska, have invented certain new,4` and. usefull' Improvements lin Spout Locks, of which the following` is a specication. A

Y This nventionrelates to improvements in devices for locking the grain spouts olf 'thrashing machines in. positions. ofiadjustment. Various devices have been proposed for .this purposeY but ordinarily` they areof a positive lnature and clearlyi and,v positively lockthe spout inV positions .of 'adjustment so that it-is necessaryto release alatch or some otherfequivlalent locking element in order to 'adjust ,theV spout. As the spout must'be adjusted frequently, ,this type of locking 'means is an inconvenient one andgenerally unsatisfactory. Furthermore, such devices are liable to become broken `dueto'the strains imposed' thereon, l thereby.: necessitatingjlre.- pairssand replacement.` Itl is, therefore, one of theimportant objects of theinvention to -provide meansfor holdingfa grain 'spoutallii position of adjustment, 'which means will permit of the spout being'swungito'any desired' position without the necessity of manipulating' any mechanicalll. parts' and whichwill at vthel same timel securely and firmly hold the spoutfiniany'lposition to Y which it is adjusted.`

- The device embodying the invention is in 'the nature of-a .frictionlock designed to hold the spout in variouspositions of adjustment -and'at the same time permitvof the spout being swung from one position to another .without the necessity 'of manipulatingany mechanical locking elements, as abovefstated, `and another important objectof the invention is to so construct the device that the same may be adjusted tooifer a greater or less degree of resistance toi'swinging'inove- .ment of the spout. Y

In the accompanying drawings;

.Figure 1 is a side elevation ofthe device `embodying the invention, installed, parts being shown in section tof'better illustrate the structure; A

`Fig.'2.is a horizontal sectional'view on the lines2-2 of Figure 1; I Y 'Fig 3 is a vertical transverse sectional viewv on the line 3 3 of lFigure '1;

In' -the"draw"ings`, the numerall indicates threaded portion `26 in general the grain spout of a thrashing machine, and the numeral 2 indicates the discharge spout of the elevator from which the grain is discharged into the spout l. The usual form of spiral conveyer is arranged within the spout 1 and as it does not constitute a part of the present invention, is notV illustrated. This conveyor how ever embodies the usual shaft, which is indicated by the numeral 3 and upon which is fixed a sprocket gear f1 having a Vsprocket chain 5 trained about it, the chain passing also about a sprocket gear 6 fixed upon a shaft 7 mounted in a suitable bearing frame 8 beneath the intake end of the spout 1. This frame 8 also mounts the usual short vertical shaft 9 upon which is fixed a bevel gear 10 in mesh with a bevel gearll upon the shaft 7 bevel gear 12 is also'fixed upon the shaft 9 and is driven from a similar lgear 13 upon a shaft 14, which shaft 14- is in turn driven from any suitable source of power supply. f

The numeral 15 indicates a fixed part o-f the frame structure of the "thrashing machine, and bolted ory otherwise secured thereto are the ends of an open 'annular friction band indicated by the numeral 16. The band 16, as will be observed by reference to Figures 1 anda 2 of the drawings, 1s concentric to the shaft 9 and consequently concentric to the axis about which the spout 1 is to be angularly adjusted. The locking means for coaction with the friction band 16 is indicated in general by the numeral 17 and the same includes two collars 18 and 19 which are clamped or otherwise secured upon the spout 1 in spaced relation. A bracket 2O is secured to the under side of the collar 18 and is provided with an opening'in'dicated by the `numerall 21, and a sim'- ilar bracket 22-is secured to the under side of the collar 19 and has a squared opening 23 formed therein. The numeral 24 indicates lin general afthrust member in the form of a rod which is of rectangular cross section throughout a portion of its length indicated by the numeral 25, and throughout the remainder of its length is of cylindrical form and threaded as indicated bythe numeral 26. The squared portion 25 ,of the thrust member is slidably fitted through the opening 23 in the bracket 22, and the is slidably 'fitted through the opening" 21 in the bracket 20.

. The squared portion of the thrust rod is providedvat! its inner end with afriction lshoe indicated by the numeral 27, and this shoe engages frictionally :igainst the outer side of the friction band 16 as clearly shown in Figures 1 and 2 of the drawings, having its engaging face curved to conform to the curvature of the said-band. Thenumeral.

28 indicates in general a second thrust member "which comprises'a bar 29V having one end upturned 'right angularly as at 30 and supporting a friction shoe indicated by the numeral 31, this-shoe bearing against the innery faceof the said band 16 and being located directly-opposite the shoe 27. A bracket`32 is secured upon the upper side ofthe bar 29 and has a rectangular opening 33slidably... receiving the squared portion 25'of lthe thrustmember 24, and the outer end rof, the said bar 29 is lupturned at right angles, as indicatedby the numeral 34 and is formed -with an opening 35 slidably receivingthe threaded portion 26 of the said thrust member 24. Aspring 36 is disposed upon the threaded `portion of the thrust member-124 and bears at one end against 'the 'upturned-'end 34 of the bar 29 and at its Jother'endl against a washer 37 which in 'turnrestsagainsta nut 38 adjustably vthreaded onto the portion 26 of the thrust member 24.V l

' From the foregoing description ofthe invention andby reference to the drawings it will be understood that. the two thrust members 24 and 28 are supported for relative sliding movement upon the spout 1 and thatf their respective shoes 27 and 31 engage respectively against the outer and inner facesof the band 16. i Itfwill'further be evident thatthe spring` 36 exerts a thrust in an outward direction upon lthe member 28 Vto hold the shoe 31 firmly against the inner side of the band 16 and at the same time exerts a thrust in an inward direction against the member 24 to hold the shoe 2? firmly in'eng'agement with the outer side of said band 16. Thus the two shoes bear with "a greater orl less degree of firmness frictionally against the faces of the band, and

this degree of pressure may be varied by adjusting the nut 38. VThus the shoes may be caused to'bear relatively lightly against the band'so as to permit of more or less freev swinging movement of the spout 1, or, by adjusting said nut 38 to further tension thespring 36,-the shoes may be caused to bear with a considerable degreel of force .against the faces of the band and render movement of the spout more difficult.

In any event, by `exerting.; the required degree offorce,the spout 1 may be swung about jits axis of adjustment to assume any desired position, and when released will be more or less.' securely held in itsposition of 'adjust ment.

Having thus described the invention, what isclaimedas new is: A f' 1. The combination with a delivery: spout supported for angular adjustment about a fixed axis, of a fixed friction member concentric to the axis, and yieldable means operatively connected with the spout frictionally engaging thesaid friction member.
